Pack for the nose

ABSTRACT

A sheet-like pack  1 A for the nose, being applicable to the skin of the nose, comprises a holding member  20  and a cosmetic material  30,  and a receding portion  6  is formed at the middle of an upper edge  2  of the pack and a projecting portion  5  is formed at the middle of a lower edge  3  of the pack. These receding portion  6  and projecting portion  5  have shapes which are fittable with each other. This provides a pack for the nose which can readily fit with the nose of various shapes, inclusive of the tip of the nose, and can contribute to an improvement in yield when manufactured in a conveyor system.

TECHNICAL FIELD

[0001] This invention relates to a pack for the nose, which is asheet-like pack of a peel-off type, has upper and lower edges havingshapes which are fittable with each other, and can contribute to animprovement in yield when manufactured. More particularly, it relates toa pack for the nose which is suitable as a pack for pores of the skin,used to remove keratotic plugs of the nose skin.

BACKGROUND ART

[0002] Peel-off type sheet-like packs are cosmetic materials of the typethat the pack is stuck on the surface of the skin with its film-formingcosmetic material surface in contact and, after it has been left tostand for a certain time until a film is formed, the film is peeled fromthe skin. Such peel-off type sheet-like packs, depending on theconstituents of cosmetic materials used there, commonly impart moisturecontent, moistening components or the like to stratum corneum when usedand absorb sebum secreted from the skin. They also impart an appropriatetenseness to the skin by the formation of film to improve bloodcirculation. They still also remove dirt, keratotic plugs and so forthof the skin when peeled. Hence, peel-off type packs are important forachieving a high emollient effect and a high rinsing effect. Inparticular, much sebum is secreted from pores of the nose skin, and thesebum may mix with stratum coneum to form keratotic plugs, so that thepores of the skin may extend, the surface of the skin may feel rough orthe tops of keratotic plugs may blacken to damage the beauty of theskin, thus the peel-off type packs are useful for the nose.

[0003] Peel-off type packs are hitherto known as jelly, pasty andpowdery products. Of these, jelly products and pasty products areapplied to the skin as they are, and films having been thus formed arepeeled. Powdery products are turned liquid by previously adding a liquidsuch as water, and the liquid formed is applied to the skin, and filmshaving been thus formed are peeled.

[0004] When these are used, however, cosmetic materials constituting apack are applied to the skin with fingers, and hence unnecessarycosmetic materials adhere to the fingers when applied, thus there is aproblem that the cosmetic materials are wasted and also the fingersbecome dirty. There is another a problem that the cosmetic materials cannot be uniformly applied to the skin surface. Also, since the cosmeticmaterials must be left to stand for a long time after they are appliedto the skin and until the formation of a film is completed, there isstill another problem that the packs are troublesome to use. Moreover,the film may have an insufficient film strength when the materials areused in a usual amount, and there is a further problem that the film maybe torn off when peeled, to remain unpeeled on the skin surface.

[0005] Accordingly, in recent years, sheet-like packs comprising aholding member such as nonwoven fabric, and a film-forming cosmeticmaterial previously coated thereon have been proposed, and put on themarket.

[0006] As forms of such sheet-like packs, some of them are provided forusers in the form of rectangular sheets so that individual users may cuta rectangular sheet into desired shapes when used, in accordance withthe portions to be packed, and some of them are previously shaped tohave outer shapes fittable with the portions to be packed. Of these, asheet-like pack shaped as a pack for the nose is known to include, e.g.,the one as shown in FIGS. 12A and 12B.

[0007] The pack for the nose denoted by reference numeral 1 in FIG. 12Ahas an upper edge 2 and a lower edge 3 which are formed in straightlines parallel to each other, and has a substantially trapezoidal outershape. The sides between the upper edge 2 and the lower edge 3 formcurves. In particular, their shoulders 4 each form a continuous curveconsisting of an arc (curvature radius: R1) curved inward and an arc(curvature radius: R2) curved outward. Also, this pack 1 for the nose isheld on a release film 40 before its use.

[0008]FIG. 12B illustrates how this pack 1 for the nose is actuallyapplied on the nose. As shown in the drawing, use of this pack 1 for thenose makes it possible to well cover almost the whole nose in the statethe pack adheres closely to the skin of the nose, compared with aninstance where a merely rectangular sheet-like pack is used.

[0009] However, each has one's own shape of the nose such as one's ownheight, width and angle of the nose, which may greatly differ from oneanother. Hence, even if the pack 1 for the nose as shown in FIGS. 12Aand 12B is used, the pack can not be applied to some part of the nose,depending on the shape of the nose. For example, as shown in FIG. 13A,the tip N1 of the nose tends to protrude from the pack 1 when one has aprominent nose and the nose has an acute angle θ. On the other hand, asshown in FIG. 13B, the ridge N2 of the nose (dorsum nasi) can not bewidely covered when one has a flat nose and the nose has an obtuse angleθ.

[0010] To cope with such problems, one may contemplate to provide, likea pack 1 x for the nose as shown in FIG. 9, a projecting portion 5 at alower edge 3 so that the tip of the nose can be covered when the pack isapplied and the tip of the nose can be surely covered however variousshapes the nose may have.

[0011] However, when the projecting portion 5 is provided at the loweredge 3 as in the pack 1 x for the nose as shown in FIG. 9, a problemoccurs such that its manufacture results in a low yield on productionlines compared with the FIG. 12A pack 1 for the nose. More specifically,when the conventional pack 1 for the nose as shown in FIG. 12A ismanufactured in a conveyor system, as shown in FIG. 11 a plurality ofpacks 1 for the nose are continuously cut out of a raw sheet 50 of thepacks for the nose, laminated onto a wide release film 40. In thisinstance, in the state the upper edge 2 of any one pack 1 for the noseand the lower edge 3 of other adjacent pack 1 x for the nose are setclosely face-to-face, the raw sheet 50 is first half-cut and then theportions not used as the pack 1 for the nose (the areas dotted out inthe drawing) are peeled off. Thereafter, the whole is cut intoindividual forms of products on the release film 40 of which each pack 1for the nose is held. Alternatively, as shown in FIG. 10, the packs 1for the nose are continuously cut out in the state their upper edges 2and lower edges 3 of mutually adjacent packs 1 for the nose arerespectively set face-to-face.

[0012] In contrast, when the pack 1 x for the nose as shown in FIG. 9,provided with the projecting portion 5, is similarly manufactured in aconveyor system, a plurality of packs 1 x for the nose are cut out inthe state they are arranged in the same direction as shown in FIG. 8, orthey are cut out in the state their upper edges 2 and lower edges 3 ofmutually adjacent packs 1 x for the nose are respectively setface-to-face as shown in FIG. 7. Here, when cut in the manner as shownin FIG. 8, it follows that a space corresponding to a height h1 of theprojecting portion 5 provided at the lower edge 3 is left between theupper edge 2 of one pack 1 x for the nose and the lower edge 3 of otheradjacent pack 1 x for the nose. Thus, the upper edge 2 of one pack 1 xfor the nose can not be brought into close contact with the lower edge 3of other adjacent pack 1 x for the nose, which can be done when cut inthe manner as shown in FIG. 11. Also when cut in the manner as shown inFIG. 7, because of a height h1 of the projecting portion 5 provided atthe lower edge 3, it follows that a large space is left between upperedges 2 and between shoulders 4 of mutually adjacent packs 1 x for thenose, so that these can not be brought into close contact. In addition,in the both cases of FIG. 7 and FIG. 8, when the areas dotted out arepeeled off, a space must be kept between the mutually adjacent packs 1 xfor the nose in order to make it possible to continuously peel off thedotted-out areas in the state they link one another. In such aninstance, however, the space between the mutually adjacent packs 1 x forthe nose must be made larger. Accordingly, in the case of this pack 1 xfor the nose, the portions not used as the pack 1 x for the nose areheld in a high proportion in the raw sheet (percentage of disposal ofraw sheets), causing the problem of a low yield of products.

DISCLOSURE OF THE INVENTION

[0013] The present invention will solve the above problems the prior artinvolves. Accordingly, an object of the present invention is to providea pack for the nose which can readily fit with the nose of variousshapes and can contribute to an improvement in yield when manufacturedin a conveyor system.

[0014] To achieve the above object, the present invention provides asheet-like pack for the nose, comprising a holding member and a cosmeticmaterial and being applicable to the skin of the nose; wherein areceding portion is formed at the middle of an upper edge of the packand a projecting portion is formed at the middle of a lower edge of thepack; the receding portion and projecting portion having shapes whichare fittable with each other.

[0015] According to the pack for the nose of the present invention, aprojecting portion is formed at the middle of a lower edge of the pack,and hence the pack can widely cover the nose of various shapes,inclusive of the tip of the nose. Also, a receding portion having ashape fittable to the shape of the projecting portion at the lower edgeis formed at the upper edge. Hence, when packs for the nose are cut outof raw sheets on production lines, they can be cut out in such a statethat the upper edge of one pack for the nose is fitted with the loweredge of other adjacent pack for the nose. Thus, the raw sheet can beused at a low percentage of disposal, bringing about an improvement inyield of products.

[0016] In the pack for the nose of the present invention, there are noparticular limitations on its layer configuration and constituentmaterials. For example, the holding member may comprise amoisture-impermeable filmy base material and the cosmetic material maybe laminated to its one surface as an adhesive layer to form a tape typeproduct, or the holding member may comprise a moisture-permeablesheet-like base material such as nonwoven fabric and may be impregnatedwith the cosmetic material, or the cosmetic material may be laminated tothe base material so as to be held thereon. In particular, from theviewpoint of promoting the film formation of the cosmetic material, theholding member may preferably be moisture-permeable. Accordingly, thepresent invention provides an embodiment in which, in the above pack forthe nose, the holding member is moisture-permeable.

[0017] The present invention also provides, as an embodiment preferredin view of layer configuration and constituent materials, an embodimentin which the moisture-permeable holding member comprises a multi-layertype moisture-permeable holding member having a water-repellent layerand a hydrophilic layer, where the cosmetic material is held in at leastthe hydrophilic layer and the water-repellent layer forms one surface ofthe sheet-like pack. In particular, it provides an embodiment in whichthe cosmetic material is a keratotic plug removable cosmetic materialcontaining a polymeric compound having a salt-forming group selectedfrom a carboxyl group, a sulfonic acid residual group, a sulfuric acidresidual group, a phosphoric acid residual group, a nitric acid residualgroup, an amino group and an ammonium group; in particular, anembodiment in which the keratotic plug removable cosmetic materialcomprises polymethacryloyloxyethyltrimethylammonium chloride.

BEST MODE FOR WORKING THE INVENTION

[0031] The present invention will be described below in detail withreference to the drawings. In the drawings, like reference numeralsdenote like or equivalent constituents.

[0032]FIGS. 1A and 1B are a plan view (FIG. 1A) of a pack 1A for thenose according to the present invention and a cross-sectional view (FIG.1B) thereof.

[0033] This pack 1A for the nose comprises a moisture-permeable holdingmember 20 formed of a nonwoven fabric of double-layer structurecomprised of a water-repellent layer 21 and a hydrophilic layer 22, anda cosmetic material 30 held in the hydrophilic layer 22 of themoisture-permeable holding member 20 and also present as a sole layer onthe hydrophilic layer 22. A release film 40 is provided on the surfaceof the cosmetic material 30.

[0034] While the conventional pack 1 for the nose as shown in FIGS. 12Aand 12B has the upper edge 2 and the lower edge 3 each of which forms astraight line, the present pack 1A for the nose is characterized in thata projecting portion 5 is formed at the middle of its lower edge 3, areceding portion 6 is formed at the middle of an upper edge of the pack,and the projecting portion 5 and receding portion 6 have shapes whichare fittable with each other.

[0035] That is, in the present pack 1A for the nose, the projectingportion 5 is formed at the middle of a lower edge 3 of the pack. Hence,it becomes possible to widely cover the nose, inclusive of the tip N1 ofthe nose, even if the nose has an acute angle θ as shown in FIG. 13A. Inthis instance, the shape and size of the projecting portion 5 may beappropriately determined according to height h, with w and so forth ofthe pack 1A. For example, when the pack has a height h of about 30 to 50mm, the projecting portion may preferably have an outer shape with awidth w1 of 5 to 50 mm and a height h1 of from 3 to 30 mm, and maypreferably be formed of an arc having a curvature radius of about 3 to40 mm.

[0036] Meanwhile, the receding portion 6 formed at the upper edge has ashape fittable to the shape of the projecting portion 5 of the loweredge. Hence, when the pack 1A for the nose is manufactured in a conveyorsystem, a plurality of packs 1A for the nose can be continuously cut outof the raw sheet 50 laminated onto a wide release film 40. In thisinstance, the packs are cut out in the state the upper edge 2 of onepack 1A for the nose and the lower edge 3 of other adjacent pack 1A forthe nose are set closely face-to-face. The space corresponding to aheight h1 of the projecting portion 5 as in the case when the packs 1 xfor the nose, having no receding portion 6 at the upper edge 2 as shownin FIG. 8, are cut out is not left between the upper edge 2 of one pack1A for the nose and the lower edge 3 of other adjacent pack 1A for thenose. Thus, it becomes possible to use the raw sheet at a low percentageof disposal and to improve the yield of products.

[0037] The receding portion 6 at the middle of the upper edge 2 not onlycontributes to an improvement in yield on production lines of the pack1A for the nose in this way, but also makes it easy to make registrationof the receding portion 6 to the route of the nose when the pack 1A isstuck to the nose. Hence, this pack 1A for the nose makes it possible toapply the pack to the nose in its optimum proper position without beingright and left out of position.

[0038] The pack 1A for the nose as shown in FIGS. 1A and 1B has asubstantially trapezoidal outer shape, having shoulders 4 formed ofcurves, in the same manner as in FIG. 9 except that it has theprojecting portion 5 at the lower edge and the receding portion 6 havinga shape fittable thereto at the upper edge.

[0039] So long as the receding portion 6 and projecting portion 5 havingshapes fittable with each other are formed at the upper edge 2 and thelower edge 3, respectively, as described above, the pack for the noseaccording to the present invention may have various outer shapes. Forexample, as shown in FIG. 3, shoulders 4 may be formed of a continuouscurve consisting of a projecting portion 4 x, a recessed portion 4 y anda projecting portion 4 z successively from the upper edge 2 side towardthe lower edge 3 side so that the air present between the pack and theskin can be easily put out to improve the adhesion of the pack by movingfingers from the top of the ridge of the nose toward the shoulders 4 ofthe pack while pressing the pack with the fingers when the pack isapplied. In this instance, the curvature radii of the curves that formthese projecting portions and a recessed portion may be appropriatelydetermined depending on the pack area covering the nose, an appearanceand so forth. For example, when the pack 1A for the nose has a height hof from 30 to 40 mm and a width w of from 70 to 90 mm, the arc thatforms the projecting portion 4 x on the upper edge side may be in acurvature radius of from 1 mm to 20 mm, the arc that forms the recessedportion 4 y may be in a curvature radius of from 5 mm to 50 mm, and thearc that forms the projecting portion 4 z on the lower edge side may bein a curvature radius of from 5 mm to 50 mm. Here, these arcs maypreferably be made smoothly continuous in view of appearance.

[0040] Air vent holes 7 may be further formed in the vicinity of eachshoulder 4 so that the air present between the pack and the skin whenthe pack is applied can be more easily put out to improve the adhesionof the pack.

[0041] The pack for the nose according to the present invention may havevarious embodiments also in respect of its layer configuration.Accordingly, the pack 1A for the nose as shown in FIGS. 1A and 1B isformed in a laminate structure constituted of the moisture-permeableholding member 20 formed of a nonwoven fabric of double-layer structurecomprised of a water-repellent layer 21 and a hydrophilic layer 22, thecosmetic material 30 held in the moisture-permeable holding member 20and also present as a sole layer on the hydrophilic layer 22, and therelease film 40 provided on the surface of the cosmetic material 30.Besides, e.g., as shown in FIG. 4, a moisture-impermeable filmy basematerial 23 may be used as the holding member 20, an adhesive layer 31comprised of the cosmetic material may be laminated to this filmy basematerial 23 and the release film 40 may be laminated thereon to form anadhesive tape type product.

[0042] Thus, the pack for the nose according to the present inventionmay have various layer configuration. In particular, it may preferablybe made up in the following way: As shown in FIG. 1B, the holding member20 comprises the multi-layer type moisture-permeable holding member 20having the water-repellent layer 21 and the hydrophilic layer 22, wherethe cosmetic material 30 is held in at least the hydrophilic layer 22 ofthe moisture-permeable holding member 20 and the water-repellent layer21 forms one surface of the sheet-like pack. Also, the release film 40may preferably be provided on the surface of the cosmetic material 30 onthe side of the hydrophilic layer 22. Since the cosmetic material 30 isheld in the holding member in this way, the pack can be prevented frombeing torn off or remaining unpeeled when the pack for the nose isapplied to the skin and thereafter peeled. Since also the holding memberis moisture-permeable, the cosmetic material 30 can be formed into afilm at a higher rate. Moreover, since this moisture-permeable holdingmember 20 is of the multi-layer type having the water-repellent layer 21and the hydrophilic layer 22, the cosmetic material 30 can be made notto come through the surface of the water-repellent layer 21 while makingthe hydrophilic layer 22 hold the cosmetic material 30, thus the packcan be not sticky and the hands can be prevented from being stained withthe cosmetic material 30.

[0043] In the present invention, there are no particular limitations onthe individual materials for constituting the sheet-like pack, such asthose for the moisture-impermeable filmy base material 23 ormoisture-permeable holding member 20, those for the water-repellentlayer 21 and hydrophilic layer 22 constituting the moisture-permeableholding member 20, and those for the cosmetic material 30 and releasefilm 40. For example, the water-repellent layer 21 and hydrophilic layer22 constituting the moisture-permeable holding member 20 may be formedof various types of nonwoven fabric, cloth, or a laminate prepared bylaminating or bonding any of these to a film. In particular, in view ofproductivity and cost, nonwoven fabric is preferred. It is also possibleto use a material obtained by subjecting such a nonwoven fabric towater-repellent treatment or hydrophilic treatment.

[0044] As the cosmetic material 30, various film-forming cosmeticmaterials conventionally used in peel-off type packs and cosmeticmaterials capable of forming a water-containing gel as used incataplasms may be used. It may also be used in the form of a pastealready containing sufficient water, or may be used in a dry state atthe beginning while supplying water content when actually used. Also, inthe case when as shown in FIG. 4 the cosmetic material is formed intothe adhesive layer 31 and this is laminated to the filmy base material23 to provide the pack for the nose in the form of an adhesive tape, theadhesive layer 31 comprised of the cosmetic material may be formed of amaterial that can be stuck to the nose as it is without feeding waterwhen used.

[0045] The cosmetic material 30 may also be made up as a cosmeticmaterial used as any of a moisture-retentive cosmetic material, asebum-absorptive cosmetic material and a keratotic plug removablecosmetic material, and may contain components in accordance with theuses. In particular, a pack for the nose which is very suitable as apack for pores of the skin, used to remove keratotic plugs of the nose,can be obtained when the keratotic plug removable cosmetic material isused.

[0046] In such an instance, as the keratotic plug removable cosmeticmaterial, in view of advantages that a film with a high film strengthcan be formed, the keratotic plugs in the skin can be gripped into thefilm and the film can be removed by peeling, it is preferable to use asa film forming agent a polymeric compound having an anionic, cationic oramphoteric salt-forming group as disclosed in the claims in JapanesePatent Application Laid-open No. 5-97627, stated more specifically, asalt-forming group such as a carboxyl group, a sulfonic acid residualgroup, a sulfuric acid residual group, a phosphoric acid residual group,a nitric acid residual group, an amino group and an ammonium group. Inparticular, those containing polymethacryloyloxyethyltrimethylammoniumchloride is preferred.

[0047] As the release film 40, for example, polyester, polypropylene,polyethylene, nylon or the like may be used.

[0048] In the present invention, any mark may be optionally printed onthe outer surface of the holding member. In this instance, what isprinted may be, e.g., as shown in FIG. 5, a line pattern 8 a that guidesthe position of the ridge of the nose when applied, or, as shown in FIG.6, a pattern 8 b of the nose. This enables much easier registration ofthe pack for the nose when it is applied to the nose.
